##[check-menu]{check menu}
!https://qcs.shsbs.xyz/api/File/raw/biniz[320x232]
the graphic check menu is already covered well by https://sudden-desu.net/entry/unused-menus-in-land-maker under "Check Menu"
by the way, "SCP" is a typo. should be SCR, referring to tilemaps.
interestingly, the format of the graphic tables used by the menu are different from other f3 games:
land maker interleaves the block definition address and filename (array of structs), while e.g. puchi carat, arabian magic, arkanoid returns, recalhorn, puzzle bobble 4, and bubble bobble ii have separate arrays for the addresses and filenames (struct of arrays).
(the array of associated palette pointers is still separate in land maker.)
##[alternate-difficulty-menu]{alternate difficulty menu}
see https://sudden-desu.net/entry/unused-menus-in-land-maker under "Alternate Difficulty Menu"
##[4-player-switch-test]{4 player switch test}
!https://pbs.twimg.com/media/EjePAEGVcAA2a0f?format=png&name=orig[320x232]
https://pbs.twimg.com/media/EjePAEHUcAAfu5H?format=png&name=orig[normal menu, for comparison]
unused code for a 4 player version of the switch test menu exists along with the normal switch test, likely retained due to the service menu being common code.
##[alternate-sound-test]{alternate sound test}
not necessarily unused, but... hold **SERVICE 1** while selecting the sound test from the test mode main menu to enter an alternate sound test with per-track volume controls for the sequenced music.
!https://qcs.shsbs.xyz/api/File/raw/qficw[320x232]
it seems a little buggy, though.
##[running-debug] running debug
!https://qcs.shsbs.xyz/api/File/raw/lgevk[320x232]
pop-up debug/test menu like in many other f3 games.
TILT: toggle [PAUSE]
hold **SERVICE 1** + press **TILT**: bring up popup [EDIT] menu
#### [PAUSE]
**P1 BUTTON 3**: (press) advance one frame
**P2 BUTTON 3**: (while held) advance frames
#### [EDIT]
**UP/DOWN**: navigation
**LEFT/RIGHT**: navigation in submenus
**BUTTON 1**: select/set
**BUTTON 2:** back/cancel
EXIT: exit the menu
SLOW LEVEL: left/right to set delay between frames
COLOR EDIT: edit color ram
DISPLAY: flip the vertical display orientation
TEST MODE: enter service menu
RESET: reset
#### [SLOW]
mode indicator displayed during delay
### mame cheat
the entry point, `$8CD70` which handles printing the mode, should be called by `$8DF32` right before the call to display credit count.
you'll also need to prevent the tilt error behavior.
(2.01)
```xml

</script>
</cheat>```
##[attack-portrait-test] attack portrait test
`$94EE6` is a disabled function that cycles through attack portrait animations when the respective player's **B2** is pressed.
we can re-enable it in its former calling task at `$94EBC` easily:
2.01
```xml
<cheat desc="Attack Portrait Test Routine">
<comment>during a match, p1 B2 and p2 B2 will cycle through attack portrait wipes</comment>
<script state="run">
<action>maincpu.mw@94EC6=0x611E</action>
<action>maincpu.mw@94EC8=0x617C</action>
</script>
<script state="off">
<action>maincpu.mw@94EC6=0x6100</action>
<action>maincpu.mw@94EC6=0x007E</action>
</script>
</cheat>```
##[p1-autoplay] p1 autoplay
near `$9C108` is (still active! task at `$9BEE0`) code that, when **P1 UP+P2 UP** are pressed, sets a demo autoplay mode flag.
**SERVICECOIN + TILT** clears the flag.
the code that handles the flag exists (`$9C132`) but is unused. the correct caller is a fairly high priority task, /not/ the function nearby: when called correctly it should constantly insert credits and continue on a loss, but the nearby code is only active during the game round.
possibly for a demonstration mode while in development? the autoplay ai properties are hardcoded: 'thinking' delay is 0 and the level is 4.
### mame cheat: (incorrect) autoplay demo
|⚠ this cheat is an /easy/ patch for demonstration, and **not the correct way to call this code**. in particular, it only runs during a round and cannot auto-continue from loss.|
2.01
```xml
<cheat desc="P1 side computer play">
<comment>hold p1 UP+p2 UP during a match to activate, TILT to deactivate. on deactivation, computer control remains in effect until end of round.</comment>
<script state="run">
<action>maincpu.mw@9C130=0x4E71</action>
</script>
<script state="off">
<action>maincpu.mw@9C130=0x4E75</action>
</script>
</cheat>```
##[map-data-edit] MAP DATA EDIT
!https://qcs.shsbs.xyz/api/File/raw/31950[320x232]
there is task code for a (partially functional) stage pattern editor from `$9F218` to at least `$9F72E`, possibly through `$9F9C3`.
however, the routine is unconnected, and has several strange patterns.
possibly missing tables, more unreferenced task loops interspersed, empty functions...
the task is called along with some other functions in debug-related code:
`$6986` to play the opening
`$698E` to map edit
`$6996` to (unknown, possibly map edit-related or for testing map)
`$699E` to run the teach demo (? uses `jsr` instead of `trap` to create task and yield)
so it's possible that these would be accessible from some kind of debug menu, but the code to create them as tasks is missing(?)
#### controls
**P1 B3**: cycle color
**P1 JOY**: grid position
**P1 B1**: place tile
**P1 B2**: recalculate coordinates?
---
**P2 B3**: clear board
**P2 UP/DOWN**: change some kind of address
**P2 START**: toggle SCROLL/START edit mode ?
**P2 B2**: `$9F560()` ?
##[location-test-text] location test text
at `$9113A`, a function to print a location test message, similar to other taito games.
!https://qcs.shsbs.xyz/api/File/raw/uxman[320x232]
```none
THANK YOU FOR PLAYING UP TO THIS STAGE.
YOU ARE A VERY GOOD PLAYER, AREN'T YOU?
BECAUSE THIS GAME IS NOW UNDER LOCATION
TEST, WE ARE VERY SORRY NOT TO SHOW YOU
THE NEXT STAGE OF THE GAME.
WE ARE TERRIBLY SORRY FOR THIS AND
HOPE TO SEE YOU AGAIN,
SOMETIME AND SOMEPLACE. ```
### mame cheat: use location test message after practice stage 3

</script>
<script state="off">
<action>maincpu.md@91026=temp0</action>
</script>
</cheat>```
##[unused-attack-pattern] unused attack pattern
there is an unused piece damage attack pattern at `$AC2F2`
!https://qcs.shsbs.xyz/api/File/raw/hwvlq[large]
it shows some similarities to ranju's final pattern:
!https://qcs.shsbs.xyz/api/File/raw/32173
there is no respective data for the select screen attack pattern preview, which uses a different format.
#### mame cheat: aifa use unused attack pattern
(in practice mode, the opponents use an entirely different set of attack patterns)
2.01
```
<cheat desc="(non-practice) aifa use unused nuisance pattern">
<script state="on">

##[music-names] music names
https://forums.insertcredit.com/d/9-lets-share-some-game-music/236
>[FlutterSprite] I don’t think there’s any official track order or track names
the arcade rom gives the following names for sequence data:
\spoiler[internal sequence name list]{
found at `$C3886C`, some kind of sequence header data. each entry is 168 bytes, which includes 4 bytes (sequence length?) followed by 16 chars sequence name. after some more header information is a series of 14 byte sequence track events(?).
n.b.: much of the text on the audio cpu has a dirty 8th bit (possibly formatting control for a display?) that needs to be masked off to read properly in ascii
```
Sequence-00
Sequence-01
Sequence-02
SELECT_R
BOSS_RI
BOSS_RL
MAP_R
Sequence-07
PUSH
SOUMEI2
Opening
Ending
HIRYU_I
HIRYU_L
Sequence-14
AIFA
SOUMEI_I
SOUMEI_L
Sequence-18
RENKI
YOUEN_R
ROHKO
RINRE_I
RINRE_L
Sequence-24
ROUCHI
LAST
```
(suffixes `_I` and `_L` indicate intro and loop sections for the same song)
placeholder sequence names (Sequence-##) most likely do not have leftover sequence data associated.}
"reZonance world〜ZUNTATA 30th ANNIVERSARY〜 L'ab-normal Limited 3" included the tracks
>{19.ランドメーカー (アーケード) SELECT BGM

23.ランドメーカー (アーケード) R4 BGM
24.ランドメーカー (アーケード) R5 BGM
25.ランドメーカー (アーケード) R6 BGM}
"R1" being 'round 1' i.e. hiryu's stage theme.
rinrei and roushinshi's stages (as well as other music) weren't present. it's not clear why.
the audio cpu, sound test, and what exists on reZonance world agree on sequence order.
|snd #|internal (adapted)|reZonance world|y's description|[#]

in 2p vs, music is determined by player character selection.
it would be appropriate to consider them respective character themes.
###[furukawa-credit] norihiro furukawa composition credit
https://twitter.com/nakayamaraiden/status/100012318167015424
>{ランドメーカーってタイトルデモ曲だけ自分が書いてたようなw}
https://twitter.com/nakayamaraiden/status/700640597476913153
>{そういえばタイトーのアドバタイズデモというと業務用の「ランドメーカー」のアドバタイズデモ曲はアテクシ担当でした（この一曲だけ）。}
norihiro furukawa (@nakayamaraiden) has claimed to have only composed the opening attract demo theme,
~~but y wonders, because of the similar name formatting, if he composed "Ending" as well~~ (pure speculation)
(2023-06-16 update:)
https://twitter.com/nakayamaraiden/status/1669648174544461824
>{アトラクトのみです。エンディングは書いた記憶ないですね…。}
"Attract only. I don't remember writing the ending...."
sorry for the misunderstanding!
##[sample-names] sample names
at the beginning of each bank is a table of instrument/sample names and the offset to the parameters for the first split.
\spoiler[on extracting samples from ensoniq sample rom]{\b{(the following examples ignore padding(?) bytes in the ensoniq rom)}
`80 [oo oo NN NN NN NN NN NN NN NN NN NN NN NN] ...`
the sample offset/name table is followed by `00 00 00 00` sentinel, then the split parameters
```c
SampleParameters {
?int16 base_freq; // in multiples of semitones, sign affects interpretation?
uint24 start_ofs; // where the sample starts in the bank
uint8 key_range_end; // highest appropriate midi key to play split at
uint24 loop_start;
uint8 loop_type; // 0=nonlooping. for es5505, 1,2,4=unidirectional, 3=bidirectional
uint24 loop_end; // loop end point (integer part)
uint8 loop_end_frac; // (?) possibly fractional part of loop end position
}```
if key_range_end < 127, additional instrument splits follow.
8 bit mono pcm.
mame uses fixed point 20.9 for sample positions.
https://github.com/mamedev/mame/blob/ae373baa246e69a52e6e8249e6e8c7897ba1e1fe/src/devices/sound/es5506.h#L236
problems: how do we convert to something preserving fractional loop points...
after determining a midi note to play at, `$C1946C` - `C194D6` determines freqcount to send to es5505 for playback.
something like this...
```asm
00c1946c 1038d834 move.b (PLAY_NOTE).w,D0b
;; at this point PLAY_NOTE is a midi note << 8, e.g. 0x3C00

##[sequencer-software] sequencer software
|🎎 to do: this needs a /lot/ more research|
(in addition to sequence playback) the audio cpu contains a lot of code and strings for what looks like a full sequencer.
#### `$C058C8`
offsets for string interpolation(function `$C0C4BA`) commands, e.g. "MIDI," "Channel," "Rename"
#### `$C05CD7`
strings constructed from interpolation:
` ENSONIQ EGOS OS Version 0.42`
`Personal Studio`
#### duart
the audio cpu writes various information out over UART as well.
`$C111D0`: duart_putchar?
`$C11276`: ensoniq_putchar? over duart
`$C11284`: ensoniq_print? over duart

##[various-unused-code] various miscellaneous unused code
|🎎 this is not a complete list!|
###[unused-prng] unused 16-bit prng?
`$00147E` (used lcg is at `$001468`)
```asm
LCG_SEED = -$77da
;; if (LCG_SEED == 0) LCG_SEED = 1
00147e move.w (LCG_SEED,A5),D0w
001482 bne.b .no_reseed

00148a divs.w #32749,D0
00148e swap D0
001490 move.w D0w,(LCG_SEED,A5)
001494 rts
```
###[counter-test] counter test?
`$9C034` counts to... various values... displaying a hexadecimal counter on the screen...
```asm
09c034 moveq #0x0,D2
09c036 ori #0x700,SR
.loop:
09c03a move.w #0xffff,D6w
09c03e bsr.w debug_count_to
09c042 move.w #0xff,D6w
09c046 bsr.w debug_count_to
09c04a move.w #0xff00,D6w
09c04e bsr.w debug_count_to
09c052 move.w #0xf,D6w
09c056 bsr.w debug_count_to
09c05a move.w #0xf0,D6w
09c05e bsr.w debug_count_to
09c062 move.w #0xf00,D6w
09c066 bsr.w debug_count_to
09c06a move.w #0xf000,D6w
09c06e bsr.w debug_count_to
09c072 bra.b .loop
09c074 rts```
after the first call of `debug_count_to(0xFFFF)`, which takes around 74 minutes, it doesn't actually stop at 0xFF. y didn't test after that.
`debug_count_to()` @`$9C076` isn't called by any other code (it's blocking, anyway).
##[unused-sprites] unused sprites

|ITMC_A01|ITMC_A02|ITMC_A03|ITMC_A04|
static versions of the arrow, star, moon, and flare items attached to an unused item base design.
the arrow looks very different from its final appearance.
moon and flare are closer to their final appearances, though the moon has no outline in this iteration.
another unused set of items (sans arrow) with no animation sequence exists

definitions `ITMD07` and `ITMD08` of the flare item are identical (i.e. reference the same 16x16 chips), and the `ITMD08` definition is unused.
###[tile-designs] tile designs
unused static tile graphics, possibly early designs? PIEAA01 is used in \link[#map-data-edit]{MAP DATA EDIT}:

this placeholder select icon is actually used... during frames after selecting a character where the respective icon flashes white (that is, it's rendered with an all-white palette over the original icon).
this is the palette used in the object viewer.

`SELSTO1A`, `SELSTO1B`, and `SELSTO1C` (not shown) are duplicate definitions to
`SELST01A`, `SELST01B`, and `SELST01C`, respectively.
it seems that at some point a stage select feature may have been planned (though it's also possible that the graphics would have just been associated with characters during character selection).
interestingly, the numbering doesn't seem to match up with the final character order.
1, 2, and 3 would be associated with hiryu, soumei, and aifa, but SELSTG04 is inappropriate for renki.
possibly:
|SELSTG04|rinrei or youen|
|SELSTG05|kouko|
|SELSTG06|rinrei or roushinshi|
|SELSTG08|renki|
there is no animation data for the SELST01 sequence,
but y shows some possible animation fanfiction for it here:

###[character-sprites] chibi character sprites
|🎎 incomplete! come back to this when animation data can be handled better. |
soumei has this rabbit-like creature encased in ice (animdata at `$E8492`):
|!https://qcs.shsbs.xyz/api/File/raw/vgyum|
|P3H1A[01-16]|
it shares the common 'frozen in ice' attack palette.
is it an easter egg? a placeholder for other frozen character sprites?

##[tile-bag-rng] tile bag and rng
|⚠ tile bag and rng behavior is /known to be different/ in the arcade mode of the playstation version. |
the prng source(`$001468`) is a linear congruential generator with (m=2\sup 32, a=7, c=5).
low bits with these parameters are not suitable, so the return value has its words swapped.
```c
uint p_rand(void) {
LCG_SEED = 7 * LCG_SEED + 5;
return LCG_SEED<<16 | LCG_SEED>>16;
}```
when a round starts, both players take their own copies of the global rng state, used only when drawing tiles. this means both players can get the same sequence of tiles at the start of the round (until becoming out of phase by rerolling, when tile color pools diverge), and do not affect each others' draws.
#### get_next_tile_color() @ $93A1C
when a tile is drawn during teach demo 1 (`stage==-1`) a special sequence of tiles @ `$939B0` is used
when a tile is drawn during teach demo 2 (`stage==-2`) a special sequence of tiles @ `$939F6` is used
otherwise:
- 1) the global rng state is saved, and the current player's rng state is loaded.
- 2) whether this is an even(3a) or odd(3b) draw is checked.
- 3a) \{the draw is even: loop over the board and construct a bitset of colors present.
store this in ram (p1: `0x40715C`, p2: `0x40715E`).}
- 3b) the draw is odd: load the previously determined valid color set.
- 4) if the valid color set is empty, the color is RED, otherwise (4b)
- 4b) call p_rand until the value passes. specifically:\{
```asm
;; if a negative random word is generated
;; the lookup takes index -2=4e75 (rts)
;; and has to go around again
select_random_from_set_loop:
; do {
; color = p_rand()

##[damage-pushback] damage and pushback
###[raw-damage] raw damage
raw damage for each piece is calculated at break time by `$96680`,
which runs once for each piece cleared, including the shot tile. (larger structures count as a single 'piece')
non-building tiles (including items) are worth 0.5 damage, but they are counted separately from building damage, so that leftover half-damage carries over between breaks.
single buildings are worth 1 damage,
structures are worth
`min(pusher_position, 7) * structure_level + structure_value`
where pusher position 0 is **fully retracted**, and position 1 looks like
!https://cdn.discordapp.com/attachments/455404849626873869/957277010512728104/32080.png
| |[*]STRUCTURE |[*]VALUE |[*] HEX |
|0| bronze | 8 | 8h |
|1| silver | 22 | 16h |
|2| gold | 38 | 26h |
|3| platinum | 54 | 36h |
table: damage values by structure level [1]
e.g. breaking 2 silvers (structure level=1), at pusher position 2
adds
` 2*1 + 22
` + 2*1 + 22
for **48** raw damage from structures
note that 7 push is almost all the way down the board;
large structures will not be able to take advantage of it.
assuming one did break a gold structure at 5 push, 5*2 == 10 extra raw damage.
-------------------------------------------------------------------------------
[1] internal tile level assigns nonstructure `0` and bronze starting at 2,
but level used in structure damage is `(internal level - 2)` (`$96696`)
[2] pusher row is stored as index into board, div 16 for position here.
###[damage-conversion] damage conversion
`$AB03E` applies received damage
raw damage is converted into two types of damage when it is sent to the opponent (represented by glowing orbs), 'piece damage' and 'push damage,'
but the conversion is affected by margin time.
the push damage conversion threshold starts at 9, meaning 9 raw damage is needed for 1 push damage.
when the round elapsed time reaches 60 seconds, the push damage threshold decreases by 1, and further decreases every 30 seconds after that, until a minimum push damage threshold of 4 (at 180 seconds) [1]
the remainder goes into piece damage, i.e.:
`push damage += raw damage / push threshold`
`piece damage += raw damage % push threshold`
in other words, <60s into a match, it takes 9 rawdmg for 1 push;
between 60 and 90s, 8 rawdmg is 1 push; and 180s+ is 4 dmg/push
note the modulo operator for nuisance tile damage:
remainder damage that doesn't go towards push goes into piece.
the push threshold influences nuisance tile accumulation!
if incoming push damage >= 3, the "DANGER" voice line plays.
-------------------------------------------------------------------------------
[1] (strictly speaking, this is a modifier that counts up and is subtracted from 9 at damage conversion time, but a view of `(9 - modifier)` as `push threshold` is simpler)
###[pushback] pushback
pushback(`$953A4`) is evaluated /whenever damage is sent/.
damage is sent on every frame that raw damage is >= 1.
(note that **all** breaks will send at least 1 damage; breaking an item (0.5(shot tile)+0.5(item)) or single tile (0.5+0.5) will both evaluate pushback.)
internally, pushback accumulates raw damage sent.
it can be thought of like an invisible meter.
"pusher [position]" refers to the amount of board covered/topmost line
- when pusher is at 0, the meter resets.
- when pusher is NOT at 0,
- the requirement for pushback is `REQ[pusher] + 2`
- the total raw damage this frame is added to the total accumulated pushback
- if accumulated pushback meter exceeds the requirement:
- the threshold is subtracted for the meter
- the push state is set to PUSHBACK
| |[*]REQ|[*]+2 |
|0| 15 | 17 |
|1| 15 | 17 |
|2| 13 | 15 |
|3| 9 | 11 |
|4| 6 | 8 |
|5| 4 | 6 |
|6| 2 | 4 |
|7| 1 | 3 |
|8| 1 | 3 |
|9| 1 | 3 |
table: pushback meter threshold lookup.
note that pusher 0 (and 9?) cannot actually be encountered.
- pusher 0 is fully retracted, and the threshold is not considered if damage is sent at this position
- pusher 9 is off of the board.
for help visualizing pushback meter accumulation and requirements, see scripts for mame and fbneo:
https://gist.github.com/y-ack/b17cd4a25b673dcfc7303ad8f5c60770
#### example
given a pusher position of 2 and initial accumulated pushback value of 0, a player makes two breaks: 1B+4, then 1S
at pusher 2, **15** raw damage is required to achieve pushback.
the first break, 1 bronze and 4 house pieces:
`(2*0 + 8) + (4) = 12`
12/15 is insufficient to trigger pushback
the second break, 1 silver:
`(2*1 + 22) = 24`
12 previously accumulated + 24 = 36
36/15 is sufficient to trigger pushback,
so pushback will occur this turn, and
(given that we have no incoming damage)
pusher position will be **1** for the next turn.
the pushback value vs requirement is now
21/17,
meaning the next shot that sends damage (any break) will also trigger pushback.
\spoiler[esoterics]{
fundamentally, the behavior of pushback is "sending enough damage will retreat the pusher." however, there are other subtle behaviors hidden in the undocumented mechanic:
firstly, while every breaking shot will evaluate damage, it is possible for damage to be counted over multiple frames. the most obvious case is with **star items**, where the shot tile and item are counted 40 frames before the tiles eliminated are counted.
additionally, it seems that there is some limit to the number of pieces that can be counted while sweeping over the board each frame, such that masses of single tiles send damage over multiple frames. damage being evaluated on multiple frames means pushback can be evaluated multiple times per break, and because there is no check for whether pushback state has already occurred, the pushback accumulator can drain multiple times with no benefit to the player.
this bug could be prevented by checking whether the push state is already PUSHBACK before checking the pushback requirement.
similarly, because **arrow items** 1) activate on break 2) set the same PUSHBACK state, breaking an arrow will drain pushback if possible, and unless there are tiles in the danger zone, this is essentially 'wasted' pushback.
the second behavior has to do with pushback evaluation being triggered by sending damage.
this is another separation of the actions of shooting a tile without sending damage (placing) and shooting a tile and sending damage (breaking).
no matter how much pushback 'meter' is stored up, the pusher cannot be repelled without making a breaking shot.
the other side of this is that pushback cannot be /drained/ without breaking tiles. this includes the behavior of resetting when the pusher is fully retracted.}
##[natural-push] natural push
after every shot, around the same time as acquiring the next tile,
the board is analyzed by `$98126`, calculating:
- **total visible piece count**
- counts of each color
- number of unique colors
- a bitset of colors present (redundantly, also generated by `get_next_tile_color()`?)
(the latter three seem to only be used for ai decision-making)
when a new natural push time needs to be determined (i.e. at the start of the round or **if natural push just occurred**), `$93740` is called to determine the number of shots before the next natural push.
this is based solely on the number of pieces visible on the board at the time.
|pieces on board|natural push in:|[*]
|0-9|1|
|10-14|2|
|15-19|4|
|20-24|6|
|25-29|9|
|30-34|12|
|35-39|15|
|40-44|18|
|45-49|21|
|50+|24|
##[arrow-item-behavior] arrow item behavior
arrow item and pushback (by damage accumulation) both set push state to PUSHBACK, which:
1) (if possible) reduces incoming push damage by 1
2) (if possible) moves the pusher wall back 1 row, revealing tiles
at some point **later, incoming push damage gets evaluated** and (if necessary) the pusher pushes forward once and decrements one incoming push damage.
when breaking an arrow item specifically, if there are any tiles in the red danger zone on the board, a special behavior is triggered that will skip push forward that turn, 'stalling' the pusher.

##[rank-calculation] rank calculation
a value separate from normal score, an internal 'rank score' is calculated on loss (by `$996DA`), determining the rank displayed on the end screen and, if conditions are met, the ending sequence shown.
`rank score = ((bronze*3 + silver*9 + gold*25 + platinum*60)^2) / ((15 - stages_cleared) * (continues+1))`
where structures are counted when broken/sent, and 'stages_cleared' is a stage counter that starts at 0. losing on hiryu's stage is 0, losing on aifa is 1, and so on, up to 10 for clearing gaira and 11 for clearing bonus.

note: `cmp2` was bugged in mame prior to 0.227, causing rank and ending selection to be incorrect.
##[vs-stage-selection] 2p vs stage selection
($8E46A)
in vs mode, the stage set is selected by:
- taking the current stage number
- adding 1
- adding a random number 0-3 (inclusive)
- quantity modulo 8
```asm
;; $8E470:
jsr p_rand.l
andi.w #0x3,D0w
addq.w #0x1,D0w
add.w (stage_num,A5),D0w
andi.w #0x7,D0w ; hiryu-roushinshi
move.w D0w,(stage_num,A5)
```
that is to say that:
a) only stages in aifa, soumei, renki, and youen pools are possible in round 1,
b) given a known round 1 stage, there are only 4 stages (16 layouts) possible in the following round 2,
c) boss/bonus stage layouts will not show up in 2p vs,
d) as an independent event, hiryu stage layouts only have a 1.5625% chance of appearing without going into the tiebreaker round.
round distributions when considered independently:

!https://qcs.shsbs.xyz/api/File/raw/mdmic[666x433;large]
!https://qcs.shsbs.xyz/api/File/raw/mlecy[600x390;large]
one of **four** /layouts/ ("openers," piece sequences) in the stage's pool is later selected randomly.

>{When changing the tempo in the middle of a song, F3 requires tempo data to be sent from the outside (main). Therefore, tempo changes are not included in the sound data itself. In test mode (as a common specification with other platforms), tempo change processing is not performed, so the default tempo of the song is played from beginning to end.}

#[emulation-notes] emulation notes
>{ - audio improperly emulated
- possibly incorrect clock timings
- effect chip not emulated(?)}
m68k `cmp2` was bugged in mame prior to 0.227, causing rank and ending selection to be incorrect.
as of mame 0.253, win messages and endings are visible thanks to this research!
the taito f3 has 4 total clip planes, and up to 2 can be assigned to each playfield.
the low bits are in 625x00 and the high bits are in the upper nybble of 624400 (1, 2) and 624600 (3, 4)
\h[previous notes on ending slides]{
>{known emulation issues (MAME 0.227)
- line ram 5600 mode is unemulated
- win messages don't display
- possibly cause of first ending slide not appearing}
ending slides have maybe a table of clip plane and playfield column scroll addresses at `$FF102`
|slide|clip 1 lo | clip 1 hi | clip 2 lo | clip 2 hi|[#]
|1|null | null | 625600(unemu) | 624600 |
|2|625600(unemu)|624600 |625400(unemu)|624600 |
|3|625400(unemu)|624600|625200 |624400 |
|4|625200 |624400 |625000|624400 |

> 僕が入った頃のタイトーはバリバリ硬派なアメコミなグラフィックがメインの会社だったんです。アニメっぽい絵を描く方が異端の存在で、その手のものをちょこちょこ引き受けて描いてました。
> When I first joined Taito, the main company was crunchy and hard-core American comic graphics. Drawing an anime-like picture is a heretic, and I took on and drew things of that kind.

>{There are two types of specifications at Taito: the pre-development specifications and the post-development final specifications. The final specifications are written after completion, so they're pretty standard, but I get the impression that the pre-development specifications are often a bit too much.}

> I've written a lot of things that look great, but at that time I had a plan and the development was discontinued. The development of Pu-Li-Ru was also once discontinued. It wasn't me who saved me, but the programmer in charge at the time who spoke directly. It is his credit that Pu-Li-Ru saw the sun
